GASOLENE-LAMP.

To all whom it may concern:

Be it known that I, ALMoN B. LEE, a citizen of the United States,residing at Big Rapids, in the county of Mecost-a and State of Michigan,have invented a new and useful Gasolene-Lamp; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention pertains to a new and useful hydro-carbon incandescentlamp, and the main object of the invention is the production of aninverted gasolene lamp of this character, which may be utilized in anyplace, as desired, in lieu of an ordinary gas lamp.

This lamp is especially adapted for lighting halls, stores, residences,and any other place where a permanent lamp fixture is applicable; thislamp may be attached to any suitable conduit, or any other hollowpiping.

Another object of they invention, is the provision of a lamp of .thisdesign, and so constructed, as to increase the lighting power of lampsof this character, and for the least possible cost.

The illumination obtained from a lamp of this design existsapproximately fifty hours from one gallon of ordinary gasolene.

A lamp of this design generates its own gas, and automatically `mixes,it with the proper amount of oxygen or cool air, which is drawn into themixing chamber or burner tube; the mixed gas and oxygen is then forcedthrough the screens to the burner and mantle, where it may be ignited,in order to obtain the proper light.

A further object is vto provide a generator tip, so constructed, as toprevent the gas orifice (which is very small) from becoming clogged,thereby eliminating the source of annoyance common in other makes ofgasolene lamps.

A further object of the invention, resides in filtering the gasolene,before the same reaches the generator tip, and its orifice.

This invention comprises further objects, which will be hereinafter morefully described, shown in the drawings, and the novel features thereofwill be pointed out by the appended claims.

In the drawing there is disclosed a sectional view through the improvedhydrocarbon incandescent gasolene lamp, which Specicaton of LettersPatent.

illustrates the essential features of the invention.

Referring to the illustration 1 denotes a valve casing having the usualneedle valve 2, which cooperates with the seat 3, in order to regulatethe supply of gasolene to the lamp. This valve casing is connected tothe gasolene supply pipe 4, which may receive the gasolene from anysuitable source of supply (not shown). Extending through this valvecasing 1 are bores 5, one located below the valve seat 3 and one aboveit, as clearly shown. The bore above` the valve seat is disposed upon anincline, in order that the mouth 6 thereof may be closed by the valve 2.

Threaded into the lower portion of the valve casing 1 is a pipe ortubing 7, the portion 8 of which is used as the generator or retort 9,as will be clearly apparent. Surrounding the pipe 7 is an annularflanged ring 10, which supports the cap or shade 11, the purpose of4which being to mnttle or confiner the heat rising from the iiame at themantle 12, about the generator or retort. The generating chamber 18 ofthe generator, has contained therein a loose packing of asbestos 14,which performs the function of a strainer or filter, through which thegasolene passes before reaching the parts below it. This asbestospacking 14 rests upon the meshwork or screen 15, below which thedome-shaped mesh work or screen 16 is disposed. This dome-shapedmesh-work or screen is carried by the lower peripheral end of thegenerator pipe 7, as clearly shown. Between the screen or meshwork 16and the dome-shaped mesh work or screen is a loose asbestos packing 17,the function of which being similar to the packn ing 14. This domeshapedmesh-work or screen acts as a covering, as well as surrounding the tubeand the cap 18 and 19. The tube 1S is hollow and open ended, the lowerhalf 20 of which being slightly tapered as shown, for obvious reasons.The tube 18 is telescopically received by the 'cap 19, as clearly shown,the closed end of which cap rests upon the upper portion of the saidtube. The function of the cap is to absolutely prevent any sediment fromentering the tube 1S and passing on through the gas orifice 21 of thegenerator tip Q2. This generator tip is connected to the lower end ofthe generating pipe by means of suitable threads 23. Disposed in thehollow portions 2st of the tip, below the extremity of the generatingpipe 7, and partially surrounding the cap 19 is a loose asbestos packing25, the function of which being to filter the gasolene. The lowertapered half of the tube 18 is telescopically received by the bore 2G ofthe generator tip, as clearly shown. The pressure of the gas whichemanates from the generating chainber is sufficient to force by the tubeand cap 18 and 19, (which are loosely disposed in the tip,) in order topass through the orifice 21.

The burner pipe. or tube 27 is connected to the lower extremity of' thetip Q2 by suitable threads 2S, as clearly shown. rlhe burner pipe ortube has formed in its circumference openings or apertures 2S), whichare disposed directly opposite one another. Extending through theseopenings or apertures 29 is a transversely disposed pipe or tube 3U,which is provided with openings er apertures 3l, the axes of which aredirectly at right angles to those of the apertures or openings 29. Theouter ends ot the pipe or tube 30 are secured by any suitable means,preferably brazing, to the annular flanged ring 32, in order to supportthe same and the globe 33, which is supported by means of the thumbscrews These thumb screws Si engage under the annular rolled fiange 35of the globe. This globe is provided with a series of openings 3G, inorder to allow air to pass therethrough, thereby forcing the heat up andunder the shade 11. The generator tip is provided. with a restrictedportion 37 (through which the orifice 21 is formed), which restrictedportion extends into one of the openings or apertures 31, in order toprevent displacement of the pipe or tube 30, as will beclearlynnderstood.

The lower threaded portion 3S of' the burner pipe or tube has connectedthereto a sleeve 39. This sleeve 39 has an annular flange 40, whichlimits the movement of the annular ring 41, which carries the mantle 12.Thesleeve 39 is provided with a screen or mesh-work 43, while the ringel is provided with a similar screen or mesh-work Llll. These screens -land al are for the purpose of preventing particles of foreign matter(which may be drawn in with the cool air or oxygen) from entering themantle, thereby obviating any possibilit-y of hindering the illuminationat the mantle. The annular flanged ring is provided with a plurality ofapertures 45, the functions of' which being similar to the apertures oropenings 36 ot the globe.

L16 denotes an alcohol cup, which is carried by the upper portion of theburner pipe or tube 27, and which surrounds the generator tip 22. Thisalcohol cup may be lighted, in order to provide heat, by which the gasis generated, before igniting the lamp. The securing of this cupapproximately at the base of the generator, is to insure a more completegeneration of gas, thereby preventing the blazing up of the gasolene,when the lainp is first lighted. its the gas from the generatordescends, the saine draws the oxygen or air through the pipe or tube 30,and thoroughly mixes in `the mixing chamber l), after which the combinedgases and oxygen descend to the mantle, where the saine are ignited.ythe heat ascending trom the mantle and the generator tip prevents thecooling off of the generator, should the lamp be suspended in a draft ofair, thereby avoiding iiclrering or unsteadiness of the light.

From the foregoing, the essential features, elements and the operationof the device, together with the simplicity thereof will. be clearlyapparent.
